My fastest session from the event, set on Sunday morning. Fastest lap was a 1:36.8. I noticed on Saturday that my tires were delaminating on the shoulders, and I was worried I wouldn't have enough tires for the event. I went out Sunday morning and tried to get my fastest lap as soon as possible. Early on, I realized I had lost a lot of grip compared to Saturday's sessions. I figured it was due to excessive tire wear. Unfortunately, my engine oil cap wasn't replaced the previous evening after some routine maintenance, and engine oil was splashing around the engine bay and dripping down onto the passenger side tires. Thus, contributing to the lack of grip. Luckily, that was the worst that happened. Still set my fastest lap of the weekend during this session.
